Making Goodyear's next-gen blimp (pictures)

The new Goodyear blimp

AKRON, Ohio -- Anyone who has ever watched a major sporting event on TV is no doubt familiar with the famous Goodyear blimp. For decades, the tire giant's airships have flown over events of all kinds, providing aerial footage even as they advertise the company's tires.

But now Goodyear is getting ready to retire its three American-made blimps and replace them with three zeppelins designed by Germany's Zeppelin Luftschifftechnik (ZLT).

Why? For three main reasons. First, zeppelins fly differently than Goodyear's traditional blimps and offer television event directors the ability to have cameras essentially hover overhead and get better, more consistent shots. Second, the new airships are quieter. And finally, they fly faster, longer, and more efficiently.

Though Goodyear announced its plans in 2011, few have seen the company's progress as it builds its new zeppelins -- which it will continue to call blimps in order to maintain the "Goodyear blimp" brand. But on Road Trip 2013, CNET reporter Daniel Terdiman stopped in at the company's Wingfoot Lake blimp operations near Akron and got a firsthand look at how the new zeppelin is coming together.

Zeppelin and its skin

Goodyear is building the new zeppelin -- which it will still market as a blimp -- inside its Wingfoot Lake airship hangar near Akron, Ohio. The company hopes to formally unveil the new airship later this year, and will begin making the second of three zeppelins in 2015. It should complete construction of the third by 2018. The three zeppelins will replace the blimps that Goodyear currently bases at Akron, Carson, Calif., and Pompano Beach, Fla.

Goodyear purchased the design, and the components for the new zeppelins from Zeppelin Luftschifftechnik, which is based in Friedrichshafen, Germany. But Goodyear is building the airships in its Akron hangar, and making several modifications to the standard zeppelin NT design.

Currently, construction of the first new blimp is well under way, with the ship's frame already put together and its skin slowly being stretched out over its full length.

The rear frame

Unlike a traditional blimp, which is essentially just a giant inflated bag, a zeppelin has a rigid frame.

Zeppelin NT

Goodyear is replacing its familiar blimps with zeppelins like this one, seen in 2008 and flown by California's now-defunct Airship Ventures. The zeppelins are designed by Zeppelin Luftschifftechnik (ZLT), from Friedrichshafen, Germany, and feature three propellers instead of two, and a design that allows the airship to hover like a helicopter. That's one of the primary reasons Goodyear is switching airship platforms, given that being able to hover over a sporting event should allow event TV directors to order specific shots.

Compared with a traditional blimp (see next photo), a zeppelin is longer and has a slightly less oval silhouette.

Zeppelin gondola

The gondola on a zeppelin -- as seen on Airship Ventures' Eureka -- is larger and more comfortable than that of Goodyear's traditional blimps. In addition to seating 12 people instead of 6, the zeppelin's gondola is also much quieter because the engines are not directly outside. That means passengers can talk normally and don't need to wear headsets to hear each other.

Up and under

A look at the underside of the frame of the new Goodyear blimp, which is being built at the tire company's Akron, Ohio, airship hangar in conjunction with personnel from Germany's Zeppelin Luftschifftechnik, which designed it.

Sliding skin over the top

Because the zeppelin has a rigid frame, it's built by first constructing the frame and then slowly stretching the skin over the top. By comparison, a blimp is made by starting with the skin on the ground and slowly inflating it.

Underside skin

Though it appears that the yellow frame is the zeppelin's bottom, it is actually only its middle. The fabric seen underneath the frame will be pulled all the way to the airship's far (rear) end, and once fully enclosed, the zeppelin will be inflated using helium, which will raise the frame up well off the floor.

Zeppelin gondola

The interior of a zeppelin's gondola is spacious, airy, and comfortable. This photograph was taken inside the gondola of the Eureka, which belonged to California-based Airship Ventures, which has gone out of business. The Eureka was dismantled and its components were sent back to Friedrichshafen, Germany, home of Zeppelin Luftschifftechnik, the company that made it, and which designed and is helping Goodyear construct its new zeppelins.

Rear propellers

Unlike a traditional Goodyear blimp, which has only two engines, mounted just outside the gondola, a zeppelin has three engines, two of which are on either side of the airship's center, and a third at its very rear. Because it has three engines, a zeppelin can hover like a helicopter.

Blimp mast

A blimp's mast, by comparison, is a much larger, more cumbersome construction, as seen here, with the Spirit of Goodyear linked up to its pyramid-shaped mast at Goodyear's Akron, Ohio, airship operations headquarters.

Another advantage -- at least to the passengers -- of a zeppelin, is that its gondola has a large rear window, which allows those on board to see behind the airship. That's how CNET's Daniel Terdiman photographed the Golden Gate Bridge from the now-deconstructed zeppelin Eureka in 2012.
